wns::scheduler::strategy::dsastrategy::FarFirst Class Reference

DSA startegy equally distributing available resources between users. If there are n resources and m users: m1 = n mod m users get floor(n/m) + 1 resources, m - m1 users get floor(n/m) resources. The resources are then granted to a user by first increasing the subChannel number, then the timeSlot, then the spatialLayer. TODO: Make it configurable in which order time, frequency and space domain are used for resource sorting.

Public Member Functions
	FarFirst (const wns::pyconfig::View &config)
virtual DSAResult	getSubChannelWithDSA (RequestForResource &request, SchedulerStatePtr schedulerState, SchedulingMapPtr schedulingMap)
	determine subChannel for request. This is only a suggestion. The allocation/fixation is done outside.
virtual void	initialize (SchedulerStatePtr schedulerState, SchedulingMapPtr schedulingMap)
	call this before each timeSlot/frame. Important to reset starting values.
bool	requiresCQI () const
	true if the strategy must have CQI information. E.g. for getBestSubChannel based on CQI
